Reply to Spectrum analysis of Guitars
I’m about to join the club- my cheap microphone I bought a year ago doesn’t work with my laptop so I just ordered the UMIK-1 Omni-Directional USB mic in Giuliano’s book. In the meantime, I’ve run REW with my PC microphone, so not posting anything until I get the UMIK.
It looks like my peaks are all lower in frequency that the lower limit in…

Reply to Black Grain Filler Under EM6000?
The EM-6000 WB topcoat and EM1000 sealer finally arrived; let the testing begin….
I’ve made a number of test panels for black grain filler under EM-6000 top coat and over Silver Tip Epoxy grain filler (including Michael Bashkin’s suggestion). I am going to update this thread with the results as the panels are completed. Materials are listed…

Reply to Celluloid Binding sources....
For the sake of future generations, I buy my celluloid binding from Rothco and Frost in the UK. Good product, reasonable cost, and shipping cost has been comparable to STANDARD US shipping.

Hey Dalton!
Have you found a better alternative than canopy glue for your ABS binding yet? I’ve had a similar issue finding an adhesive for celluloid binding repair that won’t attack NC lacquer.Karl Borum (GAL)

Reply to Locating a wrap around bridge
“…I am wondering where that extra length came from? Is that from the string travel (intonation adjustment) on the tuneomatic bridge piece?”
The intonation at the bridge is related to the stiffness of steel strings, and the differing degree of string stretch when fretted. String stretch is also why, when you check intonation at the 12th fret,…

I’m brought back to this thread, searching for more discussion on bridge materials in terms of weight and stiffness. Just read a paper by Trevor Gore* which has a brief mention of bridge woods, relating to mass (weight). In it, he identifies three woods that rated well, balancing stiffness, density and hardness: padauk (Pterocarpus sp.),…

Reply to Black Grain Filler Under EM6000?
I have been using water based filler over sealer: sealer/ black filler/ sealer/ lacquer. I may just give that a test, (but with WB lacquer) but I would love to seal my purfling lines with epoxy. My last build was a nightmare with tiny “invisible” gaps that I couldn’t see until lacquer. I could barely see them afterward with a visor + loop. …

Reply to Noob Builder Question - Router Table Woes
I route thinner material for acoustic builds so I dont have much to add except to map out the grain direction before you start, chalk works good for that. Also, a fulcrum/ starting pin can be useful to stabilize your work piece. Here is a video from Woodpeckers that illustrates the use of a fulcrum point. Many router table inserts provide…
